RE: nating

I don't run Checkpoint, but I found this from the competition: 

16.) Multiple Public Servers Mapped
Behind a Single IP Address
CyberGuard recognizes the expense
and workload of managing multiple
external addresses and therefore offers
port mapping capability which allows
multiple servers to be mapped behind a
single IP address. Checkpoint and other
security vendors require a separate
public IP address for each and every
server that is publicly accessible.

Hope that helps,

Subject: [fw-wiz] nating 


Hello,

I am using checkpoint firewall on NT 4.0.
I have a valid IP on firewall 208.122.29.72 and local 172.16.0.20.
I am using one to one NATing between valid IP 208.122.29.69 and local
IP 172.16.0.81.On local IP I am using only 119 port (NNTP ) for the
external users other services I have blocked for the external users.
I am also using web server on local IP 172.16.0.98.
Now I want to use valid IP 203.122.29.69 through NATing for web
server.
I want to use the NATing on service base.
Can we do this?. If yes please tell me in detail.

Thanks
Anand Vidhani
